SPECIFICATION forming part of Letters Iatent No. 760,841, dated May 24, 1904. Application filed November 2, 1908. Serial No. 179561. (No model.)

' zen of the United States, residing in the city of St. Louis and State of Missouri, have invented a new and useful Improvement in an Artificial- Stone Sewer-Cap, of which the following is a specification.

My invention relates to an artificial-stone cap for sewer-inlets, the object of the invention being a cap of this characterwhich shall be as durable as natural stone, cheaper, and more ornamental in appearance.

The invention consists in a cap constructed as hereinafter described, particularly pointed out in the claims, and shown in the accompanying drawings, in Which Figure 1 is a perspective View of my cap in place. Fig. 2 is a perspective view of the frame in which the cap is molded. Fig. 3 is a plan view of the cap in the frame when half completed. Fig. 4 is a perspective view of a front-edge wear-plate. Fig. 5 is a section through my cap, showing same after set in place.

The construction of my cap will be best understood by examining in detail the method of producing same.

In the drawings, A represents a rectangular wooden frame of the size and shape of the finished stone. is of a thicker piece than the other members and on its inner face is formed with a curved recess A. In the frame is arranged a block B, having an upper curved surface, and the side of the block that bears against the thickened end member of the frame is curved to fit the recess A. In its longitudinal center the block B is about three inches in height and of no appreciable thickness at the ends. 'At its ends the block is approximately six inches in width. After the block has been placed in position the frame, which may be about six inches in height, is filled half full ofconcrete, cement and sand, or crushed granite, an iron ring C,'about five inches in height, having first been placed centrally within the frame. This concrete is tamped tightly between the sides of the frame and the ring. When the stone is built up to the level of the highest portion of the block B, a chain or frame of The forward end of this frame wear-plate E has'a plurality of longitudinal slots E formed in it and both ends rounded, as at E and its outer edge E is curved to conform to the curvature of the recess A in the The wear-plateis placed in posiframe. tion on the material above the block B and additional material placed over it, filling the slots E. The frame is then filled to the top,

aportion of the filling overlapping the rounded ends E as clearly shown in Fig. 1. This and the material projecting through the slots will hold the wear-plate firmly in place. The top of the stone is then finished to a smooth surface, and as soon as it has sufliciently hardened the frame and ring 0 are removed. In about ten days the stone is ready to be placed in position. When removed from the frame and placed in position, it will be noted that the stone has the usual .manhole F, that the wear-plate is arrangedon the curved edge of the street side of the stone midway the top of the stone and the upper wall of the sewer-inlet protecting, it from breakageby contact with wagon-wheels, and that the block B has formed in this front side of the stone under the wear-plate a recess F, having an upper curved wall forming the sewer-inlet. The link-frame G gives strength tothe stone, and it will be noted that when this frame is formed of a chain the links can readilyadapt themselves to the stress, while a rigid metal frame would notgive and hollows? would be liable to form, owing to the stress separating the concrete from the frame Gr.

A stone of this construction will be found as durable as natural stone and is cheaper than natural stone cut to the proper shape and size, which would also require dressing down in order to render it neat in appearance.

Having thus fully described my invention, what I claim as new, and desire to ,secure by Letters Patent, is

1. As a new article of manufacture, an arti- 10 forth.

2. An artificial sewer-cap of the kind described comprismg a curved street-corner edge, a recess formed 1n the lower portion of said edge, said recess having a curved upper Wall, a metal Wear-plate beveled at one end and having a curved front edge, said plate having longitudinal slots produced therein and being embedded in the material of thestone above the recess, the beveled edge extending inward away from the curved edge of the stone, the said stone having a centrallyarranged manhole, and ametallie strengthening-frame arranged in the stone around the manhole.v
